6 is the provision of, a simple relatively inexpensive drop, particularly resistant to injury by shock. V i
Another object is to. provide a drop of rugged construction, compact, of light weight and eiiicient in operation under various positions of inclination.
Another object is the provision of a drop requiring a minimum of current for operation. i
With these and other objects in view the invention consists in the construction and novel combination of parts fully described hereinafter, illustrated in the accompanying drawing, and pointed out in the claims zi pended hereto, it being understood that various changes in the form, proportion, size and minor details of construction within the scope of the claims, may be resorted to without departing from the spirit of the invention.
In the drawing forming a part hereof Fig. 1 is a side view of the improved drop showing the parts in one position.
Fig. 2 is a similiar view of apart of the drop showing the parts in another position.
Figs. 3 and 4: are end views, looking at the opposite ends of the drop.
Fig. 5 is adiagrammatic view of the wiring. In the present embodiment of the invention a reset electro-magnet coil 1 is provided, and a set coil 2, the said coils being of usual construction, and arranged coaxially. The center field piece 3 is arranged between the adjacent ends of the coils. At the outerend of the coil 1 is the forward coil head a, while at the outer end of the coil 2 is the terminal block 5, the head and block being of insulating material, as for instance gray fiber.
A rear field piece 6 is secured to the ter minal block 5, in the present instanceby screws 7, and the cores 8 and 8a of the coils 1 and 2 are arranged in alinement.
is secured below the coil 1, by means of screws 10, or the like. This bar extends be yond the end of the core 8, and curves upwardly to near about the level of the axis of Mechanism is provided for limiting. droppin movement ofthe shuttertodisplay the cores as indicated at 9a,the freeend of the bar being spaced apart from the end of the core 8 as shown. r
A shaft 11 is journaled in the'arm, and the indicator drop is supported by the shaft; This indicator comprises the usual shutter 12, having means indicated at13 for supporting a name plate 1-1, and the shutter has pair of rearwar dly. extendingarms 15, WlllCll are securedto the shaft. An armature 16 is secured to the shaft in a fork of the 1, energization of the coil 1, will cause the armature 16 to move into the position of Fig. 2, through the magnetic attraction between the core and the armature, and such move ment of the armature will swing the shutter to the position :of Fig. 2, that i'swith its plane substantially parallel "with the common axis of the magnets.
position, that is :to aposition where it is substantially perpendicular to the common axis of the coils, and for holding it in the reset position of Fig-2. This mechanism includes two laterallatch projections 17 from an angula'rportion 18 on a :plate 19, secured at its rearend to an armature block 20 which is at the other a notch 24. The notch and the stop are adapted to be engagedjby aprojectionll? .in different positions. ofthe shutter,
- as clearly shown in Figures 1 and 2. 7 When the shutter isin the reset position of Fig. 2, the projections are engaged-With the notches 24L of the two arms. hen the shutter is in display position, the projections engage the stops 23. The'latches are operated to release position by the coil 2. V r
Fig. shows the Wiring diagram for the drop. The" cores 8 and 8a of the coilsl and 2 have the usual windings 25 'a'ndQG tively. Corresponding terminals 01" the coils, 2
indicated at 27 and 28 respectively are connected to a common lead wire 29; The other: terminals 30 and 31 are/ connected with-the;
positive side of the circuit, the common lead wire' bei-ng connected to the negative side. The common terminal is indicated at 32, the
reset terminal at 83, and
,The operation of the device is as follows. Normally the shutter is in the-positionc'f the set terminal at 'Fig. 2. W hen the circuit through the coil 2 is closed,by any suitable mechanism, the core 8a is magnetized, and the barQO is lifted to release the latch projection 17 from the notches 2d.
The upward movement of the PTOJBCtlODS to release position also acts to start the shutter toward indicating position,
the coil 2 beingat this time open.

.lVhat is claimed as'new is 1. In an annunciator drop having coa-xlally arranged setting and resetting magnets, a
pivotally'mounted drop normally held in reset position against the force of gravity, said drop carrying-a shutter, an arcuate armature connected to said drop, means responsive to energization of said resetting magnet to attract said arcuate armature to operation in a horizontal position, of a pivotally mounted drop normally held in reset position against the force 01" gravity, an arcuate' armature connected to said drop and movable in a path adjacent said resetting magnet, means operable inresponse to ener gization of said setting magnet to cause movement of said drop to display position,
